I agree that article is weird and plain out wrong on several points, but I didn't spot the error with the location of SE-REH. I'm 99.9999999% sure SE-REH is not going to be located in US, but apparently every bird had to be certified individually for flying in and out of US. I think it was Germanwings who almost burned their fingers some weeks ago, when a flight had to return to DUS after a couple of hours flying, because they suddenly discovered that the replacement bird they were using wasn't certified for US and had they continued they would have been facing a heavy fine.

SK stated June 15-16 which is probably close to be right.
